NdFeB Magnets-浙江东政电机有限公司

① 特点

NdFeB magnets are mainly made from Neodymium, Iron, Boron, with excellent magnetic property, abundant raw material and reasonable prices, NdFeB magnets can be used as an ideal magnets in mini-motor, permanent magnet instrument, electronic industry, auto industry, petro-chemical industry, nuclear magnetic resonance, sound device magnetic suspension system, magnetic transmission machine and magnetic therapy apparatus etc.. The disadvantage of NdFeB magnets is its weak corrosion and oxidation resistance. its surface usually is treated with some special methods. The surface treatment method include Zinc, Nickel, Tin, Silver, Gold plating and phosphor and spray epoxy resin etc..
